I don't want to solve the case when I'm a little policeman.

Chapter 666 Found the clue

Xu Zheng fell asleep while Han Rui was singing. After sleeping for two hours, he hurriedly drove to the Yuhuatai Criminal Police Brigade at 08:30.

On the way, he sent a WeChat message to Sheng Yiru and recommended the song "Changing the Wind to Travel Thousands of Miles" to her. However, when he arrived at his destination, Section Chief Sheng had not replied yet and was obviously asleep.

Normally, Xu Zheng wouldn't be so concerned about things other than the case, but after listening to this song sung a cappella by Sister Xiaorui this morning, he had the idea to use this song as background music.

He even thought that if the Propaganda Department disagreed, he would mention it emphatically while he was going to "report" the work to the ancient hall.

When the time comes, if Sister Xiaorui sees this promotional video on TV or Douyin, and the background music is her favorite "The Wind Travels Ten Thousand Miles", then she will definitely be very happy.

"Captain Lu, I'm sorry, I overslept." When Xu Zheng found Lu Shen, he was meditating in the office. It was obvious that the meeting had already been held at this point, and the tasks that should be assigned should also be assigned, but I don't know why he Still in the office.

Lu Shen waved his hand and asked Xu Zheng to sit down first. He did not ask him the reason for being late, but said with a sad face: "We also didn't sleep all night and slept for a while in the early morning. This night, we investigated Mai Jingwei All the men near the house, five of them, met the criteria of 180-185. They all had alibis on the day of the crime. We also checked this and they did not lie.

As for Mi Yu, we investigated her poker friends and relatives and found that 7 men met the criteria. Two of them could not tell what they were doing that day, but after our investigation, we found that one of them went to gamble. One is looking for excitement.

Moreover, Mi Yu was very sure that although she was not a clean woman, her only lover so far was the deceased Yan Kaibo.

There are also two boyfriends she had talked to before, both of whom are in other provinces. According to their mobile phone numbers, they had not been to Changming on the day of the incident. We have now sent a letter to ask our local colleagues to investigate. .

But I think these two people are definitely not the same. After all, they and Mi Yu have not seen each other for many years. "

Xu Zheng saw that he was a little discouraged, his mental state was not very good, and the corners of his mouth were blistered. It was obvious that he was under a lot of pressure. Maybe he would be criticized by his superiors again in the morning, "Has Team Lu been criticized by the leader again? "

Lu Shen smiled bitterly, "The leader said that today is the fourth day. The case continues to ferment online, and the Chinese New Year is approaching, which has had a great impact on Changming's tourism industry and business environment. Let us, no, let me work harder. Bundle.

I read that if the murderer of the case a year ago could not be caught, the best place for me after the year would be to be transferred to a certain police station and become an instructor. "

"It can't be so serious." Xu Zheng took a cup of hot tea, sat on the sofa, and blew in the hot air. "Is it possible? Maybe the second murderer is a habitual criminal. He didn't leave any traces at the scene. , only took away the hostess's underwear, obviously he had a lustful heart and courage, and he even dared to kill someone.

And this man must be proficient in counter-reconnaissance.

Have you checked whether there are any suspects who have recently been released from prison or are on the run for rape, burglary, theft, or even obscenity? "

When talking about the case, Lu Shen also sat up straight, "I sent someone to investigate yesterday when I came back from Forensic Doctor Lu. This is a common practice. When there is a case and no suspects can be found, we always investigate these people as soon as possible.

However, after one night, no suspicious person related to this case was investigated. "

Xu Zheng rubbed his brows and fell into deep thought. The murderer didn't take Mi Yu's cash or jewelry, nor anything else, but just his underwear. Wasn't he the kind of person who was greedy for Mi Yu?
Thinking again that the murderer did not take Mi Yu's original black silk stockings, Xu Zheng had an idea in his mind, "Captain Lu, do you think the murderer might not be the fetishist we thought.

But after he hit the deceased's head, blood spattered on his face or body. He casually took Mi Yu's underwear and wiped it. In this case, he must have taken away the underwear, right? "

There was no blood spattering at the scene of the crime. This was because the deceased's hair was long, and the main reason was the speed of the blow. However, if the murderer was hit with the second stick, then the blood must have spilled over the scalp of the deceased by this time.

In this case, the blood will definitely be stained on the grip stick, and as he swings it violently, it is normal for a few drops to splash out.

Lu Shen had been to the scene many times. He immediately found the video of the scene and watched it again, "The possibility you mentioned is not impossible. If so, the murderer would definitely not have hidden a pair of women's underwear with the blood of the deceased.

So how will he deal with it?
Either leave Mai Jingwei's house and throw it nearby, or go outside the Jiangjun Mountain area and throw it in the trash can.

Or just bring it back, wash it and throw it away.

Of course, it is also possible to put it together with the clothes and gloves he wore that day and find a far away place before throwing it away.

In this case, it will be difficult for us to find useful clues. After all, it is impossible to rummage through garbage in the city, right? "

Xu Zheng shook his head, "I mean, this murderer must be a cautious person. From the video of the entry and exit of Mai Jingwei's village that day, all vehicles and people entering and exiting have been investigated.

So obviously this person, like Mai Jingwei, was familiar with the terrain of that place and avoided surveillance by walking.

But if he had blood stains on his body, he would definitely not be able to hide it from the police dogs. In this case, he couldn't just wipe it with clothes.

I think he should go out, or simply change out of the clothes he wore to commit the crime, and either throw the clothes somewhere with water, or hide them at Mai Jingwei's house. "

On the day of the incident, Lu Shen and the others searched nearby mountains and trash cans, but found no clothes suspected to be the murderer's, and police dogs found nothing. This shows that Lu Shen said a possibility, "Is it possible that the murderer used plastic I packed the clothes in bags to block out the smell and took them away."

"It's possible, but the winter clothes are packed in plastic bags. They are a big ball. The murderer will definitely not go out like this, otherwise it will be too conspicuous and not conducive to their escape." Xu Zheng also felt a headache. Now they all believe that on the day of the crime, Mai Jingwei and the murderer escaped together.

Unfortunately, no one nearby or around Jiangjun Mountain saw them, including the cameras.

The police sent 1000 people into the mountain to search because they thought they might be hiding somewhere in Jiangjun Mountain, but nothing was found. They also sent frogmen to search the reservoir and pond south of Jiangjun Mountain, but nothing was found.

This shows that the murderer must have planned an escape route, otherwise Mai Jingwei's passion for killing people would definitely leave clues during the escape process.

"I think we should check Mai Jingwei's home again. This time, we have to dig up three feet of the ground, including their toilet, to see if there are any clothes changed by the murderer."

Lu Shen had no other choice now, so he thought he could give it a try. Before, he just investigated whether there were any suspicious traces in and around Mai Jingwei's house, and did not dig deeper. "In this case, I will report it to the leader first and let him know more." Send some police."

At ten o'clock in the morning, fifty police officers, most of whom were auxiliary police, also requested the police dog base to send three police dogs. Lu Shen asked them to search near Mai Jingwei's house.This time, we focused on investigating where the soil showed traces of movement and whether there were any clothes hidden in the soil.
In addition to Lu Shen and the others who stayed at Mai Jingwei's house, they were on-site survey experts from their branch and the city bureau. They focused on searching every place in Mai Jingwei's house, including sewers, roofs, cabinets, bathrooms and other places where things could be hidden.

Even appliances like refrigerators and washing machines have to be searched.

Xu Zheng did not take action, but walked around Mai Jingwei's house to observe where things might be hidden. If he was the murderer and wanted to hide clothes in this house, where could he hide them without being found by the police?

The first choice is definitely the sewer, and the best choice is the toilet. No, the toilet is fine for flushing small clothes, but if it's like a coat, it will definitely be blocked.

The second option is to mix it with the owner's clothes in the closet, so that it is less likely to be detected by the police. Unfortunately, Mi Yu's life is considered to be a single woman living alone, and there are basically no clothes of Mai Jingwei in her closet.

After Lu Shen and Xu Zheng checked, they both shook their heads. In Mi Yu's wardrobe, apart from the quilt, there were clothes for her and her children. Mai Jingwei only had five or six pieces of clothes, all of which had been left unwashed for a long time.

Then the third option is to go inside some debris on the second floor.

It's just that there is obvious dust on the floor tiles on the second floor. It seems that no one has been here for a long time. The murderer will definitely not come up if he sees this situation.

While Xu Zheng and the others were checking, colleagues outside shouted loudly: "Team Lu, we've found it, we've found it."

This man had a very loud voice. When everyone found him, they quickly gathered around him from a distance and covered their noses and mouths. Only when Xu Zheng came closer did they know the reason.

It turns out that the toilet used in Mai Jingwei's home is still a large plastic bucket used for the conversion of earthen toilets ten years ago as a storage place for waste water. This thing is buried deep underground. Every one or two years, the government will send People suck up the feces.

In fact, it is similar to the biogas digester that lived for a while, except that the barrel is made of plastic and is quite big.

The searchers took iron hooks and hooked them in the plastic bucket, and they actually pulled out a ball of stuff. After a brief cleaning, they found a mask, a pair of gloves and a pair of underwear, all bundled together.

The style of underwear is exactly the one Mi Yu lost.

It's just that this kind of thing has been soaked in feces for several days. Can we still detect anything useful?

Xu Zheng felt a little confused, so he immediately asked the trace inspection colleague he had followed this time, "Xu Ke, I don't know this situation, can I still find the murderer's DNA tissue?"

Section Chief Xu couldn't guarantee it and frowned, "It's hard to say. I'm just afraid that the skin fragments of the murderer may have been washed away by the water. Let's take them back and check before we talk."

Lu Shen felt that it was a good thing to find these things. He shouted to the colleagues around him: "Colleagues, please work harder. Now we have found the things that the suspected murderer used, and we also searched his jacket and pants.

Everyone, please try harder and I will go back at noon and give you a snack. "

"Eh?" No one in the crowd appreciated it, they all dispersed with disgust.

Lu Shen was stunned for a moment before he realized what he was doing. He was talking about extra meals next to the dung bucket. No wonder everyone looked disgusted.

Xu Zheng smiled and said, "Let's go, let's look elsewhere. These gloves and masks also prove that the murderer is someone else. There is no need for Mai Jingwei to wear gloves before beating people. Besides, the grip stick is on But it has his fingerprints."

Lu Shen also smiled, "Yes, today's discovery is indeed a good thing. It seems that the direction of our previous investigation was indeed wrong. Mai Jingwei did not escape by himself, but the murderer helped him avoid all the cameras and avoid pedestrian."

Near Mai Jingwei's house, both sides of the road are covered with miscellaneous trees more than one meter high. The branches and leaves have not fallen yet, and there are also such miscellaneous trees on the mountains, as well as lakes and streams. No one will bend down and escape. Notice.

Besides, there are very few people here.

Exiting Jiangjun Mountain and walking less than 1000 meters to the southwest is the Niushou Mountain tourist area. There are streams everywhere on Niushou Mountain, which provide favorable conditions for the two suspects to escape.

After all, the camera coverage in the two scenic spots is less than [-]%.

The two returned to the room, sat on the sofa, and waited for everyone to work. Unexpectedly, after a while, one of their colleagues actually made a new discovery.

What was found this time may indeed be the suspect's coat.

The coat was a black windbreaker, very thin. The colleague who discovered it was an old auxiliary policeman who smoked. He secretly smoked under a miscellaneous tree outside the yard wall and discovered that the cement ash in the corner was stuck to the wall tiles.

He gently opened it and found that there were no wall tiles inside, but a soft mass. As he took it out, he found that it was a black piece of clothing wrapped in a plastic bag.

No one would carefully remove the weeds under the exterior wall and carefully observe every corner. This time, it can only be said that it was luck. The colleagues who were surveying immediately searched the area, and even the walls above were spray-painted. Blue fingerprint contrast agent.

Not to mention, this time, with the help of contrast agent, they actually found a footprint.

Looking at the trace inspection, Chief Xu also looked happy. He put on gloves and did an inspection. "This windbreaker has not been soaked in water. It is very likely that the murderer's fingerprints, skin debris, and even... hair.

However, for further inspection, you need to go back and use equipment. "

The smile on Lu Shen's face never broke this time. If it weren't for the sake of image, he would have laughed for a few minutes. Unexpectedly, the murderer's hidden things were actually found.

He looked at the trace examiner, who sprayed the exterior and interior walls of Mai Jingwei with blue contrast agent. He felt that there would be discoveries next. If a fingerprint or a hair was found, what would happen next? Wouldn't it be easier to investigate down here?

"Xu Ke, take people back quickly and get tested immediately. Haha, let me know as soon as you have good news."
